Disorders of veins

Veins carry the oxygen-depleted blood back to the heart. Diseases of the veins cause congestion in the affected limb leading to swelling and pain. In the long run venous congestion can damage the skin and ultimately cause non-healing wounds.

Dilation and valvular malfunction of the superficial veins is the cause varicose veins (varices). Depending on their severity, varicose veins may be just a cosmetic problem, or a relevant health problem resulting in symptomatic venous congestion. Varicose veins can also lead to inflammation (“phlebitis”) and an increased risk of thrombosis.

Deep-vein-thrombosis (DVT) is an acute obstruction of the deep veins by a blood clot. DVT most frequently affects the veins of the leg and results in sudden swelling and pain of the affected leg. DVT is an emergency. If untreated, parts of the clot may be flushed into the lungs causing a dangerous pulmonary embolism. Therefore, early detection and treatment of DVT is crucial. DVT may also cause a lasting damage to the venous valves and lead to chronic venous congestion.
